The search for why large numbers of spawning coho salmon have been dying in Puget Sound's urban streams goes as far back as the 1980s and culminated this year with the discovery of a previously unidentified chemical related to automobile tires. We offer a detailed timeline for the discovery.
Environmental engineers and chemists at the University of Washington Tacoma have identified a mysterious compound implicated in the deaths of large numbers of coho salmon in Puget Sound. The chemical is linked with a rubber additive commonly used in tires and is thought to kill more than half of the spawning coho that enter the region's urban streams every year.
About the magazine
Welcome to Salish Sea Currents, an online magazine of feature stories focusing on the science of ecosystem recovery. Stories are typically grouped into sponsored series based on timely issues or events. Join us as we report on some of the key issues driving Puget Sound recovery.
This magazine is published by the University of Washington Puget Sound Institute (PSI) with major funding from the Environmental Protection Agency. To be notified of new stories, subscribe to the PSI eNews list.

A main story and 3 vignettes on the sources, impacts, and regulation of non-native species entering local waters. Sponsored by U.S. EPA and Washington Department of Fish and Wildlife.
Nearly half of the invasive species in Puget Sound's marine waters have been found within the last 20 years. Among the most common pathways for invaders are ships and boats that may carry thousands of tiny hitchhikers. Our series looks at this growing threat and some of the species of top concern.

A series covering major science themes presented at SSEC16 in Vancouver, BC. Sponsored by U.S. EPA and the Salish Sea Ecosystem Conference.
Stories exploring major research themes presented during the 2016 Salish Sea Ecosystem Conference in Vancouver, BC. See also complementary reports in SSEC16 snapshots.
An in-depth series on issues related to shoreline armoring in the Puget Sound region. Sponsored by U.S. EPA and Washington Department of Fish and Wildlife.
Salish Sea Currents presents an in-depth series focusing on shoreline armoring in the Puget Sound region. Close to a third of Puget Sound's shoreline is classified as armored with bulkheads and other structures meant to hold back storm surge and erosion. But new studies reveal the often significant toll this is taking on the environment. To be notified of new Salish Sea Currents stories, subscribe to the Puget Sound Institute eNews.
A 10-story series covering major science themes presented at SSEC14 in Seattle, WA. Sponsored by U.S. EPA and the Puget Sound Partnership.
In this first Salish Sea Currents series, we offer 10 stories exploring major research themes presented during the 2014 Salish Sea Ecosystem Conference.
New EPA-funded Implementation Strategies are designed to target Puget Sound recovery in the most direct and coordinated way ever conducted by state and federal agencies. We report on how these strategies will affect Puget Sound’s Vital Signs for years to come, and why you should care (a lot).
